6.3.6.7 MOSFET VDS Overcurrent Protection (VDS_OCP)

The device has adjustable VDS voltage monitors to detect overcurrent or short-circuit conditions on the external power MOSFETs. A MOSFET overcurrent event is sensed by monitoring the VDS voltage drop across the external MOSFET RDS(on). The high-side VDS monitors measure between the VDRAIN and SHx pins and the low-side VDS monitors measure between the SHx and SLx pins. If the voltage across external MOSFET exceeds the VDS_LVL threshold for longer than the tDS_DG deglitch time, a VDS_OCP event is recognized. After detecting the VDS overcurrent event, all of the gate driver outputs are driven low to disable the external MOSFETs and nFAULT pin is driven low. VDS level and deglitch time are programmable.
